PEIEICATION forming part of Letters Patent No. 331,386, dated December l, 1885.

Application filed May 7, 1885. Serial No. 164,657. (No model.)

To all whom it may concern:

Be it known that I, Geenen M. Baires, a citizen ofthe United States, residing at Bridgeport, in the county of Fairiield and State of Connecticut, have invented certain new and useful Improvements in Processes of Straightdeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improv einentsin the method ofstraight cning needles, wire, tubing and the like, and has for its objectto accomplish the desired result in a manner that shall be extremely ac curate and entirely automatic; and with these ends in view my invention consists in revolving the object to be straightened across the path of the straightening mechanism, and in controlling the operation of the straightening mechanism by the eccentricities of the object to be straightened.

In order that those skilled in the art to which the invention appertains may fully understand my improved method and operation, I will proceed to describe the same, referring by letter to the accompanying drawings,form ing a part of this specification, in which is shown one form of machine for carrying out my invention.

Figure l is a side elevation ofmy machine; Fig. 2, an end view; Fig. 3, a plan, the electric circuit being shown in diagram, and Fig. 4 an end elevation showing a modification of my improvement.

Similar letters denote like parts in the several iigures of the drawings.

A is the bed-plate, which supports the operative parts of the machine.

B is a standard secured to the bed-plate, and having journaled therein a sleeve, C, on which is mounted the gear-wheel D.

E is a spindle, which passes through t-he sleeve C and is splined thereto, so that any revolution of the `former will be transmitted to the latter. The inner end of the spindle is journaled within a standard, F, which is se cured to the bed.

G is a rod supported by the standards E F, on which is pivoted the heel end of the sectional nut H, confined between the collars I. This nut, when in position, engages with threads J on the spindle E, so that when the latter revolves it will have a longitudinal feed- L ing movement, as will be presently explained. The inner end of this spindle is provided with a chuck, K, or other device for holding the object to be operated upon.

L is an anvil supported by the standard M, over which the needle or wire is ted and revolved by the action of the spindle.

N and C are standards, in which is journaied the shaft P, having mounted thereon the gear-wheel Q, which is preferably of greater diameter than the Wheel D, from which it receives its motion through theidle-wheel R.

Mounted upon the shaft l?, and insulated therefrom, is a yoke, S,which forms a part of the electro magnet T; also on this shaft is loosely mounted a disk, U, of soft iron, forming the armature of the magnet and having secured to its shank an arm, V,which extends to a point over the anvil L and forms the handle of the hammer V.

X is a spring coiled around the shaft P between the yoke and armature-disk,and serves to keep the latter in its normal position out of contact with the poles of the magnet, for the purpose hereinafter explained.

Y are commutator-rings secured to and in sulated from the shaft l?, and Z Z" are their metallic brushes, secured to the bed-plate and in constant contact with their respective rings.

A is a contact-lever pivoted to the insulated post B'. The normal position of the upper extremity of this lever is in a vertical plane whose distance from the axial line of the needle or wire is constant.

C/ is a coiled spring, attached to the insulated post D and lower end ofV the lever A', and retracts the latter against the thumbscrew E by which the normal posit-ion of said lever is regulated. V

The electric-circuit, as shown in diagram in Fig. 3, is as follows: li" is the electric source from whence the circuit proceeds in a direction of the arrows c to the positive commutator-brush and its ring, from thence by the arrows d to the electro-magnet, thence by the arrows o to the remaining or negative commutator Z', by arrows f to the binding-post IOO D', through the spring C', to the contact-lever, I

and, when the latteris in contact with the needle,4from thence through the spindle E to the frame of the machine, and finally from the post G to the source by arrows g.

From the foregoing description the operation of my improvement will be obviously as follows: A needle having been inserted in the chuck the spindle is revolved by means of a crank or pulley, and will be fed backward, as before described. Now, if the needle revolving in front of the contact-lever be out of true, its eccentricities will come in contact with said lever on its upward movement, thereby complet-ing the circuit, thus vitalizing the electromagnet, which will attract its armature against the resiliency of the spring X, and as the magnet is revolving with the shaft P the disk will be caused to revolve also, thereby lifting the hammer. As the spindle continues to revolve, the eccentricities in the needle or wire will be carried beyond the contact-lever A and the circuit thereby broken, thus causing the magnet to lose its vitality and consequently its hold on the disk, which willallow the hammer to fally on the said-needle. The hammer may be assisted in its fall by a coilspring, H', attached to its handle and the bedplate. As the needle is fed in front of the contact-lever throughout its entire length, it will be made perfectly true. To return this spindle to its starting-point, it is only necessary to disengage the sectional nut from the thread on said spindle, when the latter can be readily thrown back.

It is obvious that the above-described machine may be varied considerably without departing from the spirit of my invention, and I do not wish to be limited by the same, and I have shown in Fig. 4 one of the manymoditications which may be used. In this modification the spindle and its hearings remain, but instead of the gearing, magnet, disk, &c., a solenoid, A, is supported above the anvil, and its loose armature B forms the handle of the hammer C. Now, when the circuit is completed, as before described, the hammer is raised by the magnetic intluence of the solenoid, and when t-he circuit is broken it is allowed to fall.

In the drawings I have represented the circuit as passing through the needle or object to be straightened; but this is not essential, as the lower end of the contact-lever may form the circuit-closer, and the circuit be carried from thence directly to the negative bindingpost G. Neither is it absolutely necessary that the closing of the circuit raises the hammer, as it may be the means of tripping or lowering the same, as will be readily understood.

The gist of my invention rests in the broad idea of revolving the object to be straightened across the path of the straightening mechanism and controlling the o peration of the straightening mechanism by the direct action of the eccentricities of the obj ect to be straightened.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The method herein described of straightening needles, wire, 8m., the same consisting in revolving the object to be straightened and passing it across the path of the straightening device, and causing the eccentricities of saidobject to operate the straightening device.

2. The method herein described of straightening needles, wire, Src., consisting in revolving the object to be straightened and passing it across the path of an electrically-controlled straightening device, and causing the eccentricities of said object to operate the electrical controlling mechanism.

In 'testimony whereof I affix my signature in presence of two witnesses.
